Asta immediately challenges Mars into a fight, so the Diamond Kingdom mage creates even more of his crystal-based clones. As those clones attack the rest of them, Mars creates another sword and attacks Asta the moment he destroys one of the clones. To Mars' surprise, Asta easily cuts through the crystal-based sword and swiftly charges in for another attack. The attack is strong enough to destroy Mars' armor and blow him away into the surrounding pool. Asta's strength yet again confuses Klaus, but Noelle immediately explains Asta's nature of strength while fighting against one of the puppets.[2]

Mars then recovers from the damage he took from Asta's attack by covering himself with a larger and sturdier crystal armor. He then uses the armor to attack Asta and manages to injure him. Seeing an injured Asta, Klaus yet again belittles Asta for his power where he believes that Asta got such power by luck. However, the nobleman is shocked when he notices Asta's well-built body and the boy's speech of his ambition.[3]

Hearing Asta's ambition on becoming a Magic Emperor reminds Mars of his past when he was still participating in the experiment. In contrast with his past, Mars can only remember that his purpose is to be a destroyer and tries to attack Asta again. His attack is for naught as Asta cuts through his crystal armor and renders him unconscious. Subsequently, Mars' puppets lso come to a halt, and Asta declares that it will be the Clover Kingdom's Magic Knights that enter the treasure hall.[4]
